SPECIFICATION forming part of Letters Patent No. 257,871, dated May 16, 11882.

Application filed November 1, 1881. (Model.)

To all whom it may concern: a

Be it known that I, JOHN HUMPHaYEs, Jr.,-

ol? Salem, in the county of Oolumbiana and State of Ohio, have invented certain new and useful Improvements in Pumps for Windmills;

and I do hereby declare the following to bea full, clear, and exact description of the inventi'on, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, and in which- Figure l is a side} elevation; Fig. 2, a top view taken on the line 2 z of Fig. 1; Fig. 3, a vertical section taken upon the line a: x of Fig. 2, and Fig. 4 a crosssection taken upon the line 3 y of Fig. 1. My invention relates more particularly to the introduction of a valve-seat between the top of the well and the pumping-cylinder, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and operate the same, I will now proceed to describe its construction.

Inthe accompanying drawings, A represents the valve-seat, preferably cast in one piece of metal, with a separate bottom plate, B, held in position and secured to the seat by bolts a, passing through the flanges G and D, respectively, of the bottom and the valveseat and an intervening packing, E.

' The valve-seat A has two lateral extensions, F and G, projecting on opposite sides of the seat a suitable distance, and an'extension, H, for connection with the escape-pipe. The extension F has an opening on top at its outer end, lined with a screw-thread, to receive the tains that side of the seat, at'the same time communicating with the chamberJ within the body of the extension and forming an airchamher. The extension G projects a suitable distance, and by means of a screw-threaded opening in its top near the end receives the screw-threaded end of the discharge-pipe K, that thus communicates with the chamber L within the body of the extension G.

The piston-rod M passes down through the open end of the sustaining-pipe I, which sus,

center of the valve-seat, through the chamber N, the bottom plate, B, and on into the pipe leading to the pump-cylinder. a

The center of the bottom plate, B, is provided with a threaded flange-opening, O, for connection with the thread end of the pipe leading down to the pumping-cylinder. This opening 0 opens into the chamber N.

Between the inner end of the c'hamberL and the side of the chamber N, lying partly within the body of the seat and partly within the extension G, is located a slightly-conical opening or chamber, P, the sides of which serve as a casing or hearing for the rotating conical valve or plug Q.

The chamber P communicates by a channel,

f, with the chamber N, and by the channel a with the chamber L, and by a channel, d, with the underground discharge-pipe. These chan nels must be properly located for the action of the plug Q.

The conical valve or plug Q passes from above the top of the seat A through its hottom,whereittermin'atesinascrew-threaded end, and is secured by a washer and nut, by means of which any wear can be taken up, and is covered in by the bottom plate, B. The plug is hollow, and has an opening, 6, in its side that is of suitable length, and extends about half-way around the plug, so as to embraceany two of the three openings that may be within the same half of a circle within the opening e, thereby permitting water to pass from one out of the other through the plug.

A rod, It, extends from the top of the plug to a suitable point above, where it is provided with a crank. I

In operating this device, when it is deslred to pump water from the well the plug is rotated so that its aperture 0 will embrace or co 0 incide with the channels f and c. The water will then pass from the pumping-cylinder, through the opening 0, chamber N, using chamber J and pipe I as an air-chamber, through the channelf, plug Q, channel c, and chamber L, into the discharge-pipe K.

In emptying the discharge-pipe and airchamher, when it is desired toprevent freea ing, the plug Q is rotated to embrace or coincide with channels 0 and d, when the water,

by reason of gravity, flows from the discharge-pipe out through the chamber L, channel a, plug Q, channel d, and the ground-pipe. The plug is then rotated to coincide with or embrace channels f and d. Then the water flows out of the pipe I, chamber J, and N, through the channel f, plug Q, channel (I, and discharge-pipe, thus emptying all the water above the bottom of the valve-seat.

By this construction the full benefits of an air-chamber and three-way cocks are secured, combined within a small space in a piece of cast metal solid and secured.

Having thus described my invention, I desire to secure by Letters Patent- 1. In a pump for windmills, a valve-seat provided with channels 0, (I, andf, chamber P, and a plug, Q, all arranged for communication with the pump-cylinder, air-chamber, disof an air-chamber with a valve-seat provided with a three-way cook, with which the airchamber is in direct communication, an inletopening, an escape-pipe, and a discharge-pipe, substantially as shown and described.

In testimony whereof I affix my signature in the presence of two witnesses.
